Well, you know, it does happen. I just read recently about a dog found 8 years later, because of the microchip. Unfortunately I never had Bandit microchipped, never imagined this could have happened. I feel pretty stupid for that now, and when (yes, I keep saying 'when', not 'if') he comes home, a microchip will be one of the first things we will be taking care of. I'm hoping someone has her and is taking good care of her for you. I imagine the one year mark will be a hard day for you, and I'll be thinking of you that day for sure.
Actually, here in Nova Scotia, just this past Thursday night, a black lab that had been lost for 9 months and 4 days suddenly showed up at the neighbours house, about half his weight and not in the best of shape, but he's home, he's safe. They had NO good sightings the entire time, no idea where he has been. Really weird, but very exciting for the owners. Also there was a border collie, mostly blind from birth, that got lost for a few weeks, was found with a black bear, the bear was taking care of him. Nature is truly amazing, and I'm hoping to find my baby soon, and I hope that your baby has found a safe haven as well.
